DESCRIPTION:
technology. This high-speed, low power transceiver is ideal for asynchro-
nous communication between two busses (A and B). The Direction and
Output Enable controls are designed to operate the device as either four
independent 8-bit transceivers or one 32-bit transceiver. The direction
control pins (DIR) control the direction of data flow. The output enable pins
(OE) override the direction control and disable both ports. All inputs are
designed with hysteresis for improved noise margin.
the use of this device as a translator in a mixed 3.3V/5V supply system.
driver is capable of driving a moderate to heavy load while maintaining
speed performance
whenever the input goes to a high impedance. This prevents floating inputs
and eliminates the need for pull-up/down resistors.
